Says his name is.Steve Martin I am in a criminal investigation with the treasury department.   Supposedly I am involved in a criminal investigation.  Says I  ņeed to get in touch with him ASAP to avoid action being taken against me.

yep this guy called and left me a message from the US IRS? they asked me if i got something in the mail i said no.. and i called back again because i was hung up on.. do not like being hung up on and got a hold of another guy forgot his name but empl number was 1529... lolol these people are scammers.. they need to be reported.

"Steve Martin" has called me several times re:  US Treasury problem and this was their 2nd attempt to get me to comply.  I will be brought before a magistrate, etc., etc.
Definitely a scam.

The use of the term 'magistrate' makes me think that the person is overseas

Total scam.  Originates in either India or Pakistan.

RS does not file lawsuits.  Tax disputes are civil matters.  90% of all IRS tax disputes are settled administratively.  IRS has absolutely no authority to call on local law enforcement for anything. Local law is never involved in IRS tax disputes.   If LE is necessary, US Marshals do the job.  IRS does not cold call anyone and all contacts are initiated by US mail.

DO NOT RETURN THE CALLS.  Block them.
